In the crystal structure of the polymeric title compound, {[Ba(C10H9O5)2(H2O)2]·2H2O} n , the BaII atom is O,O′-chelated by the carboxylate end of two 2-(4-carboxyphenoxy)propionate monoanions, and is coordinated by two water molecules. It also interacts with the carboxylate O atom of two adjacent monoanions; these bonds give rise to a chain structure along the c axis. Meanwhile, the carboxyl –CO2H end of the anion interacts with an acceptor site [O...O = 2.608 (2) Å]; this interaction and hydrogen bonding involving the coordinated and lattice water molecules give rise to a three-dimensional network. The eight coordinating O atoms comprise a square-antiprism around the metal atom, which lies on a special position of site symmetry 2.

In the crystal structure of the polymeric title compound, [Sr(C10H9O5)2(C3H7NO)(H2O)] n , the SrII atom is O,O′-chelated by the carboxylate end of two 2-(4-carboxyphenoxy)propionate monoanions, and is coordinated by a water molecule and a dimethylformamide (DMF) molecule. It also interacts with the carboxylate O atom of two adjacent monoanions; these bonds give rise to a zigzag chain along the a axis. Meanwhile, the carboxyl –CO2H end of the anion interacts with an acceptor site [O...O = 2.629 (4) Å]; this interaction and hydrogen bonding involving the water molecule [O...O = 3.191 (5) Å] give rise to a three-dimensional network. The eight coordinating O atoms comprise an irregular polyhedron around the metal atom. The Sr atom, the water O atom, and the N and O atoms of the DMF molecule lie on a special position of site symmetry m; the DMF molecule is disordered about the mirror plane.

In the title compound, [Cu2(C7HF4O2)4(C12H8N2)2]·2H2O, the CuIIion has a square-pyramidal coordination sphere. The basal plane consists of two N atoms [Cu—N = 2.008 (3) and 2.032 (3) Å] from the phenanthroline ligand, and of two carboxylate O atoms [Cu—O = 1.942 (3) and 1.948 (3) Å] from two 2,3,4,5-tetrafluorobenzoate anions. Another 2,3,4,5-tetrafluorobenzoate anion provides the apical carboxylate O atom [Cu—O = 2.262 (3) Å] and bridges two CuIIions into a binuclear centrosymmetric dimer. Intramolecular π–π interactions between one of the tetrafluorobenzene rings and the middle of the phenenanthroline rings [3.617 (3) Å] stabilize the molecular configuration. O—H...O hydrogen bonds between the lattice water molecules and the unbound carboxylate O atoms of the metal complexes leads to the formation of a chain structure parallel to [100].

The central structural motif of the title coordination polymer, [Co(NO3)2(C4H4N2)(CH3CN)2(H2O)2]n, is a chain composed of CoIIions linked by bis-monodentate bridging pyrazine ligands through their N atoms. The CoIIion is located on an inversion center and is additionally coordinated by two O atoms of water molecules and two N atoms of acetonitrile molecules. The resultant N4O2coordination sphere is distorted octahedral. The linear cationic chains extend parallel to theaaxis and are aligned into layers parallel to theacplane. Nitrate anions are situated in the space between the CoIIchains and form O—H...O hydrogen bonds with the coordinating water molecules, leading to a three-dimensional network structure. Weak C—H...O hydrogen bonds are also present between pyrazine or acetonitrile molecules and the nitrate anions.

In the title salt, [(CH3CH2CH2)2NH2]4[Sn(C2O4)4]·H2O, the SnIVatom of the stannate anion is located on a special position with -42msymmetry. It is eight-coordinated by four chelating oxalate anions. The dipropylammonium cation possesses mirror symmetry while the lattice water molecule is disordered about a position with -42msymmetry and has an occupancy of 0.25. In the crystal, the anions and cations are linked by N—H...O hydrogen bonds, forming a three-dimensional network. This network is futher stabilized by weak O—H...O hydrogen bonds involving the water molecules and oxalate O atoms. The crystal studied was refined as an inversion twin.

The arsanilate anions and the water molecules of solvation are accommodated between the layers and are linked to them through a primary cation N—H...O(anion) hydrogen bond, as well as through water O—H...O hydrogen bonds to brucinium and arsanilate ions as well as bridging water O-atom acceptors, giving an overall three-dimensional network structure.

In the title compound, [Ni(C3H10N2)3]2[Ni(C3H10N2)2(H2O)2]Br6·2H2O, one Ni2+cation, located on an inversion centre, is coordinated by four N atoms from two ligands and by two water O atoms. The other Ni2+cation, located in a general position, is coordinated by six N atoms from three ligands. In both cases, the Ni2+cation has an octahedral coordination environment. The overall structural cohesion is ensured by three types of hydrogen bonds, N—H...Br, O—H...Br and O—H...O, which connect the two types of complex cations, the bromide counter-anions and the lattice water molecules into a three-dimensional network.

Abstract K2Sb4S7 · H2O crystallizes in the triclinic system with a = 1171.4(5) pm, b = 952.0(5) pm, c = 715.6(5) pm and α = 99.36(5)°, β = 86.80(5)°, γ= 103.48(5)°. One half of the Sb atoms has three sulfur neighbours forming with the free electron pair a ψ-ShS3 tetrahedron, while the other half is coordinated by four S atoms to build a ψ-trigonal SbS4 bipyramid. These polyhedra are connected by common edges and corners to a three-dimensional network with two types of channels, in which either K+ ions only or K+ ions and water molecules are located.
